How Does a Kenyan Coffee Farm Like Hania Shape Its Beans?

Chania and Oreti Estates on Kenya's Thika Plateau are among the few large private coffee farms in the country, managed by the Harries family since 1904. The French Mission Bourbon grown there keeps original Bourbon character, and natural processing brings caramel, vanilla, mixed fruit and a berry finish. Quantity is limited, with a relatively high defect rate but solid flavor in the cup.

The estate lies at 1,525 meters on red volcanic soil at the foot of the Aberdare Range, with reservoirs and riverbank forest on the grounds. About 40 employees work there, many across three generations. Green bean grading, the roast curve and pour-over parameters all matter when brewing this natural lot, so drip methods suit it well.

01| Estate Introduction

Chania and Oreti Estates are among the few large private coffee plantations in Kenya, and have been managed for coffee production by the Harries family since 1904. These two estates are adjacent to the Chania River, with reservoirs and dams built within the grounds, and cover nearly 200 acres of land, with forest planted along the riverbanks to provide shelter for birds and wildlife.

The current estate owner, Boyce Marquis Allen Harries, took over the family business of Estates and A.I.R. (Harries & Son Ltd.) in 2013. Currently, 40 employees work for Boyce, many of whom have served the Harries family for three generations. The employees have their own elected committee, which meets monthly to discuss community safety, social, and health issues. In addition to caring for their own workers, the Harries family has also donated land to the Thika City Council and participated in co-founding Wabeni Technical Institute, which teaches practical skills such as garment making, mechanics, and carpentry to help local residents gain the ability to make a living.

02| Origin Introduction

Kenya's Thika Plateau

Kenya is located in the central highlands east of the Great Rift Valley. Kiambu is one of the main coffee-growing areas, while Thika belongs to a secondary region. This area lies at the foot of the Aberdare Range, with red volcanic soil rich in organic matter. Because the Kiambu area has a mild climate and moderate rainfall, coffee farmers can harvest twice a year—from May to July and from September to December.

Some large coffee estates are located in the Kiambu area, and smallholders are closely connected with their cooperative organizations. Most have their own processing plants, which gives growers a better option than selling through unified purchasing. Farmers complete green bean processing at their own factories and can obtain reasonable prices at auction.

The unique red volcanic soil of Hania Estate, combined with suitable temperatures and rainfall for coffee growing, plus the superior natural environment, creates the unique flavor of Front Street Coffee's Kenya Thika Hania Estate French Mission variety.

03| Green Bean Analysis

Around 1892 to 1893, French missionaries brought the Bourbon variety into Kenya for cultivation. This native Bourbon variety is called French Mission Varietal, and it was not improved through scientific methods during cultivation, preserving the most original Bourbon flavor.

Kenya's "SL28" and "SL34": In the early twentieth century, French and British missionaries and researchers selected and bred direct Bourbon-line varieties in Kenya. Over the past century, they have adapted to Kenya's high-phosphoric-acid soil and produced the distinctive acidic spirit of Kenyan coffee. Top Kenyan coffees come from these two varieties, but when transplanted elsewhere, they easily lose their flavor.

Kenyan coffee grades are divided into seven levels according to bean size, and into six levels by flavor from top to bottom. Kenya's best coffee grade is Peaberry (PB), followed by AA++, AA+, AA, AB, and so on in order. Superior coffee is bright and glossy, delicious, and slightly winy. In terms of flavor, "Kenya AA" is especially well received.

Graded according to bean size:

The best Kenyan coffee grade is Peaberry (PB), followed by AA, AB, and so on in order.

PB (PeaBerry): This is the grade for small round beans. It refers to coffee cherries that develop only one bean instead of the usual two.

AA: This is a relatively common grade. The beans are larger, with a screen size above 18 mesh or 7.22 millimeters. These beans usually fetch the highest price.

AB: This grade combines A (screen size 16 mesh or 6.80 millimeters) and B (screen size 15 mesh or 6.20 millimeters); it accounts for about 30% of Kenya's annual coffee production.

04| Processing Method Introduction

This Front Street Coffee Kenya Hania Estate French Mission Bourbon coffee bean is processed by the natural method. During the refined natural process, it adds body and sweetness to Bourbon coffee that is already rich and varied in acidity. This natural lot is limited in quantity and is a coffee that depends entirely on natural climate conditions.

05| Roast Analysis

The bean density is medium. The roast climbs with medium heat, and during the roasting process the beans heat up quickly, so we lower the heat at 150°C, 160°C, and 170°C to extend the Maillard reaction time while avoiding too rapid a temperature rise. First crack begins at around 8 minutes 15 seconds, at 186°C; at the same time, lower the heat and open the damper wide to develop flavor, then drop the beans at 194°C after 2 minutes.

Roaster: Yangjia 600g semi-direct fire (roast batch 300g)

Preheat the roaster to 170°C and charge the beans. Set the damper to 3, turn on the heat after 30S, adjust the heat to 140, keep the damper unchanged, turning point 1`28``, maintain the heat. At 140°C, lower the heat to 110 and open the damper to 4. At 4`20``, turn yellow, the grassy smell disappears, and it enters the dehydration stage; lower the heat to 90 and keep the damper at 4. At 150°C, 160°C, and 170°C, lower the heat again to 90, 70, and 50.

At 7`50``, dehydration is complete. The bean surface shows wrinkles and dark streaks, and the toast aroma turns into coffee aroma, which is the prelude to first crack. At this time, listen carefully for the sound of first crack. At 8`13``, first crack begins; open the damper fully to 5 and adjust the heat to 30. After first crack, develop for 2 minutes, then drop at 194°C.

This Front Street Coffee Kenya Hania Estate natural French Mission Bourbon coffee has a good flavor, but the defect rate is relatively high, so please sort carefully before roasting. The dry aroma has natural fermentation, dried fruit, and vanilla notes. On sipping, you can taste caramel, vanilla, mixed fruit, a solid juicy body, and a finish of berries, rich jackfruit, and coffee floral notes. Overall it shows a wild African regional flavor, suitable for sipping slowly in small mouthfuls; the complex aroma is hard to let go of~
